Re: Oryx Class Diagram

Well, the batch layer reads input from Kafka. It writes the input to HDFS, but also reads previous input from HDFS and uses all of it to build a model. The model is sent to a different Kafka topic. (It is also written to HDFS actually, in case other apps want to consume it that way.) Serving layer reads the Kafka topic to get the model. Serving layer can also write input to the input topic. No, nothing reads from HDFS except the batch layer.
